i COMBINATION TOOL Application med December 7, 1922. Serial lto. 605,457.

Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Combination rIools, of whichthe following is a speciication.

The present invention relates to improvements in tools and in particular to that t e.

in 'which the operating member is ma e up of separable sections capable of adjustment with respect-to each other or assembly into diierent forms to take care of variations in the work which is-to be done with the implement and the accessibility of the objects operated upon.

@ne of the primary objects in view is the provision of a combination tool embodying quickly detachable securing means whereby the sections of the tool may be easily and quickly removed, extended, modiied as to form, or reduced in size to enable the most compact arrangement when not in use. l

It is further an important feature of m invention to provide an implement of suc component parts as will make it universal in its adaptations and the character of Work which it will per-form.

With the above and other objects in view, the invention consists in certain combinations and arrangements of the parts as will more fully appear as the vdescription proceeds, the novel features thereof being pointed out in the appended claims. l

In the drawings: l

Figure 1 is a side elevation, with parts in section, of an embodiment of this invention including a universal joint unit, with a brace form of operating handle and showing in dotted lines a modified arrangement of the end handle section for changing leverage. A

Figure 2 is a side elevation of the implement with one ofthe angle sections omitted.

Figure'3 is a detail View of the actuating elements of the universal joint section or unit.

Figure 4 is a sectional view on the line k'4--4 of Figure 2, showing more clearly the joint.

F1gures 5 to 12, inclusive, are elevation views of different adaptations of the tool,

r both as regards form and attachments.

t em apart.

Figure 13 is a view in elevation on? one of the forms of this implement showing the detachable units separated, one from the other. s

Figures 14, 15 and 16 are detail .views of the socket, ratchet and chuck attachments, respectively, used in connection with this device.

Corresponding and like parte are referred to in the following description and indicated in all or the views of the draw-A ings, by likereference characters..

The implement which is the subject matter of this invention is especially useful in the field of automotive engineering tor'the purpose of imparting rotation to nuts,

screws, drill bits, or the like, and where -very often greatv diculty is experienced by. mechanics in Working, due to inaccessi ility of parts or the oints of attack,

I will first refer to t e form of device which is clearly shown in Fi' es 1 and 3 to be composed of the knob unit 1, the

angle handle section 2, the ip section 3, the right angle section 4, t e coupling 5, and the universal joint section 6. Each of the sections 2 and .4 have male ends within which are seated spring' actuated balls 7 designed to be received in the annular grooves 8 of the female ends of the parte 1, 3 and 5. vThe sections 2y and 4, furthermore, are hexagonal, or otherwise polyi l sided or splined and the sockety ends 1n whlch these are inserted correspondv in shape so that it is possible to arrange one sectlon at a different angle to another. One'- end of such tool is formed circular so that the knob 1 may rotate thereon as usual in this class of tools. In the assembled im-\ lement ofFigure 1, the operating handle 1 s in the formof a brace, but should this form not provide suicient leverage 4it is an easymatter to shift the section 2 into the position shown in dotted lines, thereby very materially increasing the leverage obtainable. v

It will, of course, be understood that to assemble these component parts, it is' only necessary to slip the ends thereof one into the other, thus depressing the ball members which spring into the grooves referred to and interlock the parts against 'accidental dis lacement but readily permit the arts to be separated by merely pulling f example, a screw driver vbit (not shown) `which is secured to a fixed bushing or the shank part of the tool attachments which are disclosed in the several figures of the drawings.

The universal joint section 6 is composed of a shankY 6 surrounded by a sleeve 6b 6c at one end and a bushing 6? at the other end -formedintegrally with the clamp extension 6 carrying a c oo lerating clamp extension 6g loosely mounte on a universal joint element 6h. This element 6l1 is connected in turn to a cooperating 'oint element 6i having the shank 6a exten ing therefrom. The coupling 5 is rotatable within the bushing 6 and removable therefrom when the parts are assembled as in Fi ure 2.

A socket member o conventional form, desi ated 9, may be mounted on the' end, as s own in dotted lines in Figure 1 where the tool is desired to be used in'connection with the screwing or unscrewing of bolts and nuts, and the ov e'ratii'ig angle of the joint may be adjuste the position which is required for the tool to best erfor'm the actuating function.

' It wil of course, be understood that thel .separable parts of this implement hereinbefore described are designed primarily tof form a art lof a mechanics kit of tools or accessories. and in Figures 15 and 16 I have illustrated two very useful attachments wlhich go to makel the equipment most comp ete.

The first of these attachments designated 10, is a simple ratchet attachment by means vof which partial rotation of the operating tool or handle are made eli'ective, the attachment not bein herein more specifically set forth vinasmuc as it forms the subject matter of my co-pending application vfor im rovements in ratchet attachments for too s, filed of even date herewith.

The second of these important attachments `11, shown in Figure 16, is a chuck attachment, and as with regard to the attachment 1 0, no specific description of this element is embodied herein as this forms the subject matterof my co-pending application for improvements in `chuck attachv ments for tools, filed of even date herewith.

. Referring to Figures 5 to 12, it will be observed that in Figure 5 the tool is in the `form of a bracecarrying as its operating at will according tol member the chuck attachment 11. Figure 6 is the same except that the ratchet attachment 10 is introduced between the handle and the chuck. Figure 7 constitutes the tool formation of Figure 5 with the right angle section of the handle omitted and Figure 8 is the same embodiment with the ratchet attachment 10 embodied therein between the grip piece and the chuck attachment. Figure 9 is a further ada tation in which the combinationtool inclu es a umversal joint section and the chuck section. Figure 1() diiiers merely in the inclusion of the ratchet attachment between the operating handle and the universal joint section. Figure 11 depicts the tool combination of Figure 9 with the right'angle hanrdle section omitted, while Figure 12 incorporates in this arrangement the ratchet attachment 10.

In reference to the arrangement shown in Figure 2, the couplin' 5 'is removed and the grip section 3 is the end of the sleeve of the universal joint section 6. I preferabl broach straight knurls immediately wit in the socketr end of the sleeve 6", as shown atm in Figure 1, and corresponding knurls y, on the' sleeve 3* of the grip piece interlock therewith so as to rigidly connect the two sleeves together. This in effect prolongs the handle or grip portion of the tool when arranged as in Figure 2.

It will be quite apparent from the forcgoing description that the combination tool, herein described is capable of taking careof a large variety of functions requiring the rotation of the implement for performing lthe work, It iscomprehended that other attachments Ymay be employed not herein speciically set forth and, therefore, it is within the purview of tthis invention to modify the `arrangements without departing from the spirit of said invention and' Within the scope of the claims hereto. appended. n

Having thus described m invention, what I claimoas new and desire to secure by Letters Patent, is: f

l. A tool of the class described comprising a detachable shank section rovided with an angular male end, a han le rotatably mounted upon the other end of saidvsection, a coupling section having sockets at its opposite ends into either of which irectly inserted into i said male end isinterchangeably disposed,

a second shank section provided with an angular male end to iit the sockets of the couplin section, a grip piece rotatably mounted uponsaid cou ing section, and a tool carrier constructe' to be detachably interlocked with one Jend of said second shank section or with. an end of the coupling section. i

2. A wrench device -comprisingu shank sections, a coupling section adapted to interchangeably receive the shank sections for disposal in different langular relations, a gripping .section having sockets to receive the shank sections and provided with a peripheral interlocking face, a member to engage the article to be turned, and a universal joint unit adapted to be arran ed between the shank sections and the mem er for engaging the article to be turned and formed with a socket to receive the end of the coupling section and also adapted to interlock With said peripheral face of the gripping section. p

3. A Icombination tool of the class described comprising a grip section having a freely rotating sleeve thereon having straight knurls broached thereon, an' attachment for engaging the object to be operated and comprising a sleeve in which the knurled end of the i section engages, said sleeve being interior y correspondingly knurled whereby the 'two sleeves are interlocked together, and handle means adapted to be connected to the other end of the grip section.

In testimony whereof I ax my signature.
